Joe,
Get a copy of EN 60073 - 1993, (IEC 73 - 1991) - it is
a good reference. BSI publishes it as BS EN 60073.
I doubt it is adhered to entirely by most manufacturers
these days, but some of us still do. Like most everything
in the Compliance world, it is at least open to dogged
interpretation discussions, and perhaps individual
concessions.
UL/EN60950 reference this, so check there for more
supporting verbiage ("Colours"; clause 1.7.8.2).
Best regards,
Stephen

Would anyone know of an equivalent (ETSI) requirement for the EU,
and possibly rest of world, for the Telcordia requirements in GR-474 for LED
color assignments? The EU requirements are most important although any
additional information would be helpful. I would appreciate it if your
answers could be accompanied by a document number, section, etc.
The following is from GR-474:
2.2.3.2 NE Display - Visual Assignments and Meanings
R2-36 [36] The colors red, yellow or amber, green, and white, indicating the
severity of the trouble, shall be used on the NE's physical control/status
display panel to visually represent various alarm levels and status
conditions at the NE's equipment location and the OC. (See Section 2.7,
Maintenance Person - NE Interface.)
R2-37 [37] Color assignments for physical panels shall be as follows:
... a. Red shall indicate a critical or major failure, error, or danger.
... b. Yellow or amber shall indicate a minor failure, caution, warning, or
temporary malfunction, or state for which the craftsperson should use
caution.
... c. Green shall indicate satisfactory operation, active condition, or
completion of a process or procedure.
... d. White shall indicate a neutral condition that implies nothing about
the success or failure of system operations.
Thx,
Joe
